Rogers CLTE-MW High Frequency Laminates Introduction In the world of advanced electronics, where performance and reliability are non-negotiable, material selection is foundational. CLTE-MW copper clad laminate stand out as a premier choice, delivering proven excellence in dimensional stability and ultra-low planar Coefficient of Thermal Expansion (CTE). This unique combination provides consistent, predictable performance for critical components like embedded resistors, achieving among the lowest variance available in PTFE-based laminates. With a legacy of success alongside Resistor Foil technology, CLTE-MW is the trusted substrate for next-generation communications and radar systems. CLTE-MW PCB substrate is engineered to solve the complex challenges of high-frequency, high-reliability designs. Its tried and tested performance makes it a top selection for ground-based and airborne systems where failure is not an option. Core Features & Benefits: Exceptional Dimensional & Thermal Stability: With remarkably low thermal expansion (10 ppm/°C in X, 12 ppm/°C in Y, and 34 ppm/°C in Z-axis), CLTE-MW ensures minimal movement during thermal cycling. This translates directly to high plated through-hole reliability and reduced stress on interconnections. Ultra-Low Loss at High Frequencies: Featuring a Loss Tangent of just .0012 at 10 GHz, CLTE-MW enables reduced circuit losses without sacrificing its renowned dimensional stability, maximizing signal integrity in sensitive RF and microwave circuits. Stable Dielectric Constant (Dk) Over Temperature: The material’s consistent electrical properties across temperature variations lead to reduced stress attachment to ceramic active devices, such as GaAs chips or ICs, enhancing assembly yield and long-term performance. Versatile Cladding & Backing Options: Available with a full range of cladding types—including electrodeposited, reverse treated, and rolled copper foil—CLTE-MW also supports heavy metal backing (aluminum, brass, copper). This versatility supports reliable designs with embedded resistor networks and effective thermal management. Consistent Thin Laminate Availability: Offered as a reliable and consistent thin laminate down to .0003”, it supports the development of complex, high-density multi-layer boards for miniaturized, advanced packages.
